STEEL WHEEL.

described and particularly pointed'out in the, claims.

In the accompanying drawings- Figure 1 is a sectional view of the wheel. Fig. 2 is a side elevation of -a portion of the wheel.

Fig. 2 is a detail. Fig. 3 is a sectional view of the hubwith a portion of the wheel in place thereon.

Fig. 4 represents a portion of the wheel and'a coacting portion of the hub.

Fi 5 is a face view looking at the parts of Flg. 4 from the right hand side thereof.

Fig. 6 is a detail view of aportion of the hub, and

Fig. 7 is a detail view of a portion of the shell.

Fig. 8 shows in two views a split locking washer.

In Fig. 1, 8 indicates the body of the wheel which is formed of sheet metal, this body portion consisting of an annular 'portion arranged in a plane substantially at right angles to the axis of the wheel and a portion 9 continuous with the portion 8 but extending at an angle laterally from the plane of the portion 8, this annular portion being curved at 10 and merging into an overhanging rim portion 11 which is arranged substantially centrally over the annular body part 8 and is provided with a flange 12 at its terminal edge.

The edge of the rim 11 opposite to the edge atwhich the flange 12 is located is devoid of a flange and this enables a .demountable rim and tire 13 to be sli ped into place and held by clips 14 whic are retained by bolts 15 passing through the angular extension of the annular body portion 8. The body portion 8 is formed continuously with spokes 16 and 17 These spokes are cut from the body of the metal and one series 16 extends to the right in Fig. 1 and the other series extends to the left and these spokes alternate with each other andtheir lower ends are connected with the right hand and left hand ends of the hub or shell 18 by any suitable means such as by the rivets 19.

The arrangement is such that the rim of the wheel is substantially over the larger inner end of the hub. In Fig. 1 the spokes 17 are in a plane substantially at right angles to the axis of the wheel though these spokes 17 may be inclined to a sharper degree than illustrated in said Fig. 1.

In Fig. 3 I show the wheel shell or center 18 mounted on the hub 20 so as to turn with said hub as one body. therewith. For this purpose the shell is provided with a notch or cut out portion 21 which fits over a fillet 22 on the hub 20 adjacent the flange 23. The outer end of the shell 18 is provided with an inwardly extending projection 24 which fits into a notch 25 in the hub 20 andthus the shell 18 ,is held against circumferential movement in relation to the hub 20. The shell 18 is held against axial displacement in relation to the hub by a nut 26 which has a base or flange portion 27 lying over the end of the shell 18' and'restraining 1t against axial displacement. The nut 26 is screw threaded at 28 into the end of the hub 20. Roller bearings are provided at 29 between the hub and the axle 30.

Inmanufacturing these wheels it may be found after assembling the wheel on the hub that there is a slight eccentricity of the edge of the rim in relation to the. center of rotation. In order to compensate for this the rim is initially provided with extended projections indicated in Fig. 2 and if the eccentricity is found to exist the wheel then will be mounted on a mandrel and these I projections ground down to a common diameter which will insure the wheelbeing concentric. In Fig. 8 I show a split locking washe which fits between the threaded section of the nut and a shoulder on the hub. as indicated at m in Fig. 3.

I claim as my invention:

1. A steel wheel having an annular body portion near its rim lying at its inner part trally in relation thereto, said rim being 1 flanged at its inner ed e, the outer edge of saidrim being flange ess, and means for holding a tire demountably on said rim,

5 substantially as described.

2. A steel wheel having an annular body portion lying substantially in a planev at right angles to the axis of the wheel, arim portion overhanging the body portion and 10 connected therewith by a continuation of said body portion extending at an angle from the body portion and merging into the outer edge of the rim, and spokes integral with the body portion and arranged in two series the members of which alternate with each other and diverge in respect to each other,

and a shell connecting with the inner ends of the spokes, substantially as described.

In testimony whereof I aflix my signature. LAWRENCE MERLE RICKETTS.
